Remarks. I have united with Sigillaria pachyderma, Brongniart, Sigil- 

 laria scutellata of the same author. This species is not uncommon in some 

 localities in Britain, and from the examination of numerous specimens I have 

 been unable to discover any fixed character by which the two species can be 

 separated. 



I am further inclined to regard Sigillaria Candollii, Brongniart, as also 

 referable to Sigillaria pachyderma. The figure of this species given by 

 Brongniart does not appear to have been taken from a well-preserved 

 specimen, and the leaf-scars are scarcely different from those of his Sigillaria 

 pachyderma or Sigillaria scutellata. The specific characters of Sigillaria 

 Candollii seem to be more dependent on the state of preservation of the fossil 

 than on any real structural peculiarity. 



The large trunk figured by Liiidley and Hutton as Sigillaria pachyderma 

 ( Fossil Flora, vol. i. pis. liv. Iv.) is not sufficiently well preserved for specific 

 determination.
